I guess there's a meta question of what's thru-running, but if a train ran from Long Island to Newark and back, I would describe that as thru-running.

Seems to me that it is, in essence, thru-running?

I’m going to keep buying older and older cars until I end up driving a wood-fired locomotive.

A Steep Mountain Drive, a Brake Failure and a Volvo Recall A longtime Volvo fan’s terrifying ordeal prompted warnings from regulators and heightened scrutiny of software patches for electric vehicles and plug-in hybrids.

Call me a boomer, but cars should have emergency brakes that can be manually activated. And of course knobs on the dash for anything important (not just a screen).

The abundance movement has rapidly gained traction as voices across the political spectrum seek to overcome artificial scarcity in housing, energy, and infrastructure. In all these areas, transportation policy is a binding constraint —yet with limited exceptions, it’s one the movement has overlooked. This Article seeks to fill that gap by showing that abundance cannot succeed without rethinking transportation policy from the ground up. While this suggests a big lift, it offers big rewards: once reconfigured, transportation policy can be a powerful accelerant of abundance.
At present, the signature goal of abundance advocates—amping up housing production—stands to collide with a key driver of scarcity: development restrictions fueled by traffic concerns. Building more housing in auto-dependent regions without reconfiguring transportation will reinforce the very logic of those restrictions. A mechanical application of the prime abundance directive—build more—would thus miss the mark: outside the exceptional case of high-speed rail, “more” is often the problem. (See urban renewal.) But “less” isn’t helpful either. What’s needed is a new approach.
Drawing on original interviews with leading transportation officials and scholarship in local government law and planning, this Article makes two key contributions. First, it proposes a theory of transportation for abundance. Abundance suggests that more is better, but its canonical accounts falter when defining the desirable “more” and what’s needed to support it. This Article intervenes with a concrete and scalable framework from urban planning: transportation access, which measures system performance by the ability of users to reach destinations. Though seemingly uncontroversial, anchoring policy in this objective would mark a revolutionary departure from a century of transportation planning.

"Transportation for the Abundant Society," new with Jonathan Levine (Umich urban planning), now under submission at law reviews.

In the abundance literature, transport is massively undertheorized relative to housing. We show why deferring action on transportation jeopardizes the larger project.

I don’t think this works, given the UK’s more monocentric structure. Manchester (or Birmingham, if you like) have been likened to Chicago, but after that it breaks down IMO. London itself contains a ton of diversity; my neighborhood knowledge is a bit dated but there might be an analogy there.

Tesla found partially liable for fatal 2019 crash, hit with $200 million in punitive damages The outcome is a stunning rebuke for Tesla, which for years has fought to absolve itself of responsibility when its technology is involved in a crash.

Because this project will be fully grade separated, it should be built as automated light metro (e.g., Toulouse Metro, Milan M5, Honolulu Skytrain). This can enable:
—More reliable & often faster service
—More frequent service
—Shorter platforms (& thus cheaper-to-build stations)

At a high level, the issue is that the social media anti-trust attack on abundance was that it was interpersonal from the start, not even factional let alone factual. I've seen this a lot over the years in housing discourse online and its just baffling. Picking bad fights for no reason.

Law (specifically, ex ante litigation risk mitigation) predominates here. Cf. a corporate board getting a fairness opinion from an investment bank for a deal well over market price, or a bank requiring an independent appraisal before making a home loan that is straightforward on comps and LTV ratio.
